The integral type switch board
Technical field
The utility model relates to the vibration control test system (being electric vibration table) in the environmental mechanics test, is specifically related to the integral type switch board of vibration control test system.This integral type switch board is with power amplifier and the vibration control system device in conjunction with the one that constitutes.
Background technology
Existing electric vibrating control pilot system (being electric vibration table), as shown in Figure 1, generally be made up of three parts on the whole: electronic stage body, power amplifier and vibration control system, this three is interrelated again independently of one another.Divide strong power part and weak current part in the described power amplifier, strong power part is a power unit, and weak current part is a power amplifying part (power model) etc.; And vibration control system is made up of computing machine, controller, charge amplifier etc.
The concrete principle of work of electric vibrating control pilot system is: vibration control system sends little drive signal after power amplifier amplifies, driving electronic stage body vibrates and tests, on the electronic stage body sensor is installed, sensor is gathered vibration signal in real time, and give vibration controller with signal feedback, vibration controller is adjusted drive signal according to this signal that feeds back, thereby forms the control of close-loop feedback type between the three.
During work; power amplifier and vibration control system need the operator to operate and monitoring in real time; and may produce bigger noise in the electronic stage body and the cooling system course of work thereof; therefore in line with the attitude that people-oriented, for protect the operator healthy, reduce and may produce the extraneous factor of harm the operator; now all be that power amplifier and vibration control system are placed in the laboratory (or claiming soundproof room), and electronic stage body is placed outside the laboratory.Power amplifier and vibration controller are put independently of one another, but have the following disadvantages:
Though the two is placed on 1 power amplifier and vibration control system in the same laboratory, both are separated from each other the position, also need long cable to link to each other between the two, exist the hidden danger that cable easily artificially is not intended to step on the damage of disconnected or other situations;
Though the two is placed on 2 power amplifiers and vibration control system in the same laboratory, both are separated from each other the position, arrange in the laboratory to have taken bigger space;
Though the two is placed on 3 power amplifiers and vibration control system in the same laboratory, both are separated from each other the position, and in emergency circumstances simultaneously operand power amplifier and vibration control system may cause machine breakdown or personal injury thus.
In addition, if power amplifier and vibration control system simple superposition are placed in the cabinet, just need lay a fairly large number of power model to the system that power requirement is bigger, the size of module is certain, therefore how shared the more casing volume of power model be big more, because the height of casing is conditional, the adding of display makes power model part casing be restricted, wasted the space that originally can lay more power models, restricted on the whole device output power range, therefore, how reasonable, compactly power amplifier and vibration control system are struck up partnership, be one's own profession technician's a research topic always.
Summary of the invention
The utility model is placed apart for the power amplifier and the vibration controller that solve the prior art existence, the stube cable line that brings is fragile, take up room big and the two unhandy technical matters simultaneously, and a kind of novel device that combines power amplifier and vibration controller---integral type control device is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of integral type switch board comprises a cabinet, divides the vibration control system part on top and the power amplifying part of bottom in this cabinet; In the described vibration control system part, up and down or about be set up in parallel main frame and controller, the upside of main frame and controller or downside are established drawer type upset liquid crystal display device structure, this drawer type upset liquid crystal display device structure is: left-right symmetric fixedly installs supporting surface in cabinet, be provided with an erecting frame between these two supporting surfaces, fixed installation one LCD on the erecting frame, this LCD faces up when horizontality or down, the relative supporting surface of described erecting frame is hinged in the above-below direction upset, this upset pivotal motion pair is slidingly connected at the relative supporting surface of horizontal fore-and-aft direction, on the sliding path of the relative supporting surface of erecting frame, be provided with the strong point to the upper support erecting frame, constituting the following of drawer type LCD with this turns over or last turning mechanism, make LCD have horizontal storage and the vertical or two kinds of duties of demonstration that tilt, be blocked in the front side of main frame and controller in duty LCD vertical or that tilt to show; Establish power amplifier in the described power amplifying part.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described erecting frame rear portion is provided with a sliding panel, and erecting frame rear end and sliding panel front end are hinged in above-below direction upset, these sliding panel both sides again and between two supporting surfaces logical drawer guideway constitute and be slidingly connected.
2, relatively such scheme also has second kind of scheme, promptly about be arranged with in parallel on two supporting surfaces before the chute of end closure, the corresponding chute in erecting frame rear end is provided with rotating shaft, the rotating shaft two ends are corresponding embed in the chute hinged be slidingly connected.
3, the strong point described in the such scheme is the support roller that is fixedly installed on the erecting frame forward lower part.
4, in the such scheme, described support roller periphery is surrounded by the little plastic layer of friction factor.
5, in the such scheme, also be provided with a Key board drawer in the described cabinet, keyboard is set in Key board drawer.
6, in the such scheme, described supporting surface comprises following several concrete condition: the one, and it directly is meant the medial surface of regulator cubicle; The 2nd, it is provided in a side of independently supporting surface of two in the cabinet; The 3rd, it is provided in a side of two sidewalls on the base for supporting in the cabinet.
7, in the such scheme, the notion of described front and back is that opening direction with cabinet is preceding definition.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, since the utility model with the display switching mechanism, during use the display switching mechanism pulled out and turn over to a side, the time spent does not push it in casing, its shared box height only is the thickness of LCD, saved the space greatly, can put into the more power module, promptly increase the output area of power.
2, because this use new display switching mechanism is pulled out the turning height to human eye in back, made things convenient for people's observation.
3, since the utility model vibration control system and power amplifier are placed in the one cabinet, rational in infrastructure, reduce cause because of cable is long because of improper use or the artificial probability that is not intended to damage.Thereby and can operate the generation that vibration control instrument and power amplifier have been avoided mishap simultaneously.
4, because the utility model with the three-dimensional placement of vibration control system and power amplifier, its compact in design, has been saved the space.
5,, thereby reduced interference because the utility model is placed apart with strong power part and weak current part.
